TO ALL WHOM IT MAY CONCEHN:

Be it known that we, A. B. CANDEE, of Hamden, in the county-of NewHav'cn, and L.,S. TAYLOR, ot Southington, in the county of Hartford, andState of Connecticut, have invented a new Improvement in Machine forMaking Axle-Nuts; and we do hereby declare the following, when taken inconnection 'with the accompanying drawings, and the letters of referencemarked thereon, t'o be a full, clear, and exact description ofthe same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1,V atop view,

Figures 2, 3, 4, and 5, detached views to illustrate the operation,

Figure 6, transverse section through the dies, and'in Figures 7 'and 8,perspective views of axle-nuts, such as are manufactured by thismachine.

This invention isdesigned for the manufacture of the nuts which are usedupon the outer end of carriageaxles, for the purpose of securing thewheel thereon, and the invention consists in the arrangement of a pairof dies which receive and cut eti' thel blanlr from the'bar of heatedmetal, and transfer the. said blank toa position opposite the requisitepunches, and by the operation of which said punches thenut is formed inthe same die which'transiers the blank.

To enable others to construct and use our improvement, we will-proceedto describe the same as illustrated in the accompanying drawings.

A is the bedplate, supporting, in bearings B B and C C, two shai'ts Dand at right angles to each other, and the two geared together, so asto-revolve at equal, velocities.

F is one part of a die, operated by a cam, G, on the shaft D.

I H is t-he otherpart ofthe same die, operated by acum, I', on the shaftE through a rod, J, Aworking against the outer end of the die H. I

The die is formed or attached to the inner endof whatI are termed dies Fand H, and are arranged so that when in the position as seen in iig. 1,the heated bar is placed before the die F through a block, K; then, asthe machine is in operation, the die H moves upto andgrasps the rodbetween the two dies F and H g then the'said two dies advance togetherto the position in iig. 3, cutting oii` the blank from the bar as itbearsaganst the openingthrough the block K. Having been thus cutandtransferred to this point, there is arranged, at right angles to thesaid two dies, apunch, L, fixed to a slide,'M, operated'by a cam, N, thesaid punch L being constructed so as to give to the inner end of the nutthe proper form, as seen in iig.` 7 or 8; and the said punch, movedforward iuto'dies F and H, forces the metal intothe said dies to'formthe exterior of the nut; then a punch, a, within the punch L, is forcedforward by a cam, P, and pierces the nut; then, the punches retreating,the dies open, and discharge the completed nut, receive a new blank, andoperate as before described.

The cut-o` block K is arranged so as to be removed, as occasion mayrequire, for repairs, or when it has become wornrby the cutting od"ofthe blanks against itsinner surface.

"Having thus fully described our invention, what we claim as new anduseful, and desire to secure by Letters Patent, isil Thecornbination'oil the cut-oliv block K, griping-dies F and H, die L, andpunch a, all constructed, arranged,

and operating in the manner substantially as described.
